Hi there!
I am reading Hayt Engineering Electromagnetic 9th edition. Please find the attachment below I'm solving the problem D7.9 on page 218. The equation (46) is just B = Curl(A). Just for clarity, the parameters in the cylindrical coordinates are ρ: radial distance, Φ: the angle measured counterclockwise from the x-axis, and z: the distance along z-axis.
There is a current flowing along the z-axis through a solid conductor having radius a. The problem gave A at ρ = a. Then, it asks me to find A at ρ =0.
However, I got a different result from the textbook.
Could you please tell me why?
Many Thanks!
